Add new "python-no-pyc" test

This test validates that the Python images do not contain any pre-compiled `.pyc` or `.pyo` files in `/usr/local` (or `/opt`, for good measure). Ideally this would also include all of `/usr` (not just `/usr/local`) but then it would also have to filter out results that are from Debian packages (`python`'s default variants are `FROM buildpack-deps` which includes a fair amount of Python packages).
